Lady Gaga Cancels Rest of Tour Due to Injured Hip

Lady Gaga has canceled the rest of her tour dates due to a hip injury.

Live Nation Global Touring said in a news release Wednesday that Lady Gaga has a tear in her right hip that will require surgery, followed by a recovery period.

The pop star’s website showed 21 dates through March 20 remaining on her "Born This Way Ball" tour schedule. Fans who have already bought tickets will receive a refund beginning Thursday.

Lady Gaga postponed four dates on Tuesday after experiencing difficulties Monday during her concert in Montreal. The singer’s show is high energy with non-stop dancing. She explained to fans on Twitter that she’d hurt herself while performing some time ago.

She wrote: "I hid it from my staff, I didn’t want to disappoint my amazing fans. However after last nights performance I could not walk and still can’t".

Gaga has not tweeted since.

A news release announcing postponements Tuesday said the 26-year-old singer, whose real name is Stefani Germanotta, was suffering from synovitis, an inflammation of the joints. She underwent tests Wednesday morning that showed she had a labral tear in her right hip, however. The labrum is a layer of muscle that helps holds the ball-shaped hip joint in place. The news release says the surgery will require strict downtime.

The tour, in support of her second album "Born This Way," began last April in Asia and was one of 2012’s highest grossing.

Pollstar reported the tour made more than $161 million in 2012 with an average attendance of more than 31,000, making it the fifth-highest grossing tour.

An anonymous source allegedly close to the New York City Pride organization claims that Lady Gaga will be speaking at the event on Friday night, marking the pop star’s first public appearance in months.

Lady Gaga made her first major public appearance since undergoing a hip surgery that cancelled the remaining dates on her world tour tonight, at a rally on the Hudson River, officially kicking off Gay Pride.
